1 //
2 // CSL interface and main() function for use with CRAM: the CREATE Real-time Applications Manager
3 // See the copyright and acknowledgment of authors in the file COPYRIGHT
4 //
5 // The CSLService class is the wrapper used to manage CSL programs from CRAM.
6 // This file has the main() function that starts any of a number of different CSL services under the control of CRAM.
7 //
8 // Usage:
9 // CSL_Server service_name listener_port emergency_port CSL_function [-o UDP_IO-port] [-i RemoteFrameStream-in-IP/port]
10 // The name and l/e port arguments are used by the CRAM management system
11 // The CSL function is a string to select from the built-in play routines (see the list below)
12 // Examples
13 // CSL_Server CSL31 12345 12355 bells -- play bells sending sound out to the local server
14 // CSL_Server CSL31 12345 12355 speakers -o 33123 -- play voices listening for client requests on port 33123
15 // -- mix stereo sample streams from the two given servers
16 // CSL_Server CSL31 12345 12355 mixer -i 128.111.92.51 12445 -i 128.111.92.60 12445
17 //
18 // The CSL_Function selects from the various available services:
19 // bells texture of random FM bells
20 // noise swept filtered noise
21 // speakers phoneme streams
22 // mixer 8-in 2-out network mixer
23 //
24 // The optional arguments
25 // -o port-num -- for UDP_IO clients, to tell them their listener ports
26 // -i client-IP client-port -- for processors, to identify their inputs
27 // -a -- for auto-start (run stand-alone without waiting for CRAM start message)
28 //
29 // The mixer takes additional arguments to describe its clients
